Siding



Patented Aug. 22, 1950 UNITED sTATEs PATENT OFFICE- Herbert Abraham, New York, N. Y., assignor to The Ruberoid Co., New York, N. Y., a. corporation of New Jersey Application October 4, 1947, Serial No. 777,987 a claims. (c1. 2o5

L This invention relates to sidings, and more particularly to insulated sidings for covering the outer walls of building structures. 1

is well known to those familiar with the manufacture of insulated sidings, such sidings are composed of a sheet or panel of fiber-board. usually un-pressed board made of suitable fibrous material, which board is impregnated or partially impregnated, and coated on its outer surface, with asphalt or the like. A facing of naturally or artificially colored mineral granules is embeded in the surface-coating. y Heretofore insulated sidings have generally been embossed or formed in the appearance of bricks or rough stones with intervening mortar lines. The boards have been ship-lapped along allfour edges so that when applied to the sides of a building they provide a iiush, vertical, surface in simulation of masory.

While insulated sidings of that type are popular and extensively used, they are not entirely satisfactory from an esthetic point of view since they present a relatively at, artificial, appearance that lacks the depth of, and is subject lto other disadvantages as compared with, masonry side-walls. Y

Afxation of simulated brick or stone insulated r`board sidings requires the use of a large number of. nails to fasten each individual panel. It is customary practice in many instances to use from .eighteen to twenty nails, more or less, for each panel. All of the exposed nail-heads are usually Aco'untersunk with a nail-set and touched up' or covered with caulking cement. Proper nailing is very' important to effect satisfactory results. g

Wooden clapboards have been used for siding buildings `since early colonial days. However, in comparisonwith insulated board sidings they are more expensive to maintain since they require paintingy at rather frequent intervals for the sake of appearance and to preserve the wood. Moreover, they do not have the durable waterproofing, or the desirable thermal insulation properties of insulated board sidings, nor do they have the yprotection against leakage afforded by the ship- -lapped side joints of such sidings.'

Having in mind the defects ofV prior art sidings, it is the principal object of this invention to ,provide an insulated board'siding that closely 'simulates vthe appearance of wooden clapboard, with the advantages, among others, of low upkeep cost, and increased protection against the Ieilects of weather. rain, snow, and wind.

Another object of the invention is the provision of a siding that can be applied with relatively few nails, all of which are concealed.

A further object is the provision of a siding of the character described that can be utilized either for new construction work, or to be laid over old wooden clapboards or wooden shingles, previously applied.

A still further object is to provide a siding embodying novel means for fastening down the overlapped portions of succeeeding courses.

These, as well as other objects and advantages of the invention, will appear more fully from the following description thereof, reference being had to the accompanying drawings, in which:

Figure 1 is a face view of a part of a covering formed of the siding elements of this invention;

Fig. 2 is a face view, on a larger scale, of one of said siding elements;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 1;

Fig. 4 is a fragmentary detail sectional view of two lapped siding elements showing the fastening means; and

Fig. 5 is an exploded, perspective, view of the same.

The siding elements are each formed of a rec-J tangular piece of fiber-board I0 of greater length than width, which board is saturated or impregnated with asphalt or other suitable waterproof and weatherproof bituminous composition, and coated on its upper or outer surface with a coating layer Il of like substance but generally of a harder consistency. A facing of mineral granules or grit l2 is embedded or partially embedded in the coating. For the purpose of the present invention it is preferable to use granules of a uniform color, such as white or light gray, but granules of other colors, or mixture of colors, may be used. Sidings of this general character are well known in the art and are commonly termed insulated sidings.

Conventional insulated sidings, such as imitation brick or stone sidings, are ship-lapped along all four edges so that when applied they are ilush with one another to form a vertical wall covering in which all of the siding elements lie in a single, common, plane. Conventional wooden clapboard sidings are rabbeted on their upper and lower edges but not on the lateral edges, which edges are merely butted together when applied.

In the practice of my invention, I provide each siding element with a pair of ship-lap lateral edges I3 and I4, and a rabbeted lower longitudinal edge l5. sidings of this form, when applied the overlying strips will' butt against'a' part Q1' said upper edge of the underlying strips. "By reason of the fact that the lower rabbeted end of the strips of the overlying course are supportedv or partly supported on the upper edge of the strips of the underlying course, the strips of each course will be canted in the manner of con ventional clapboards. The portions wand IB of the rabbeted edge l5 form substantially a right angle. A

The upper edge I1 of each siding strip is secured to the sheathing or frame I9 of the build' ing wall by a row of nails 2D driven substantially parallel and close to the upper edge so that the nail heads will be wholly concealed by the over:- lapping portion I1 of the rabbeted lower edge' of the'strips of the next upper course. As-shown ve nails may be used to secure each strip, but fewer nails may be used, and no exposed nails are required such as are used in applying insu-l lated bric-k sidings.

In addition t0 nailing, I may provide associated fasteners 2| for anchoring each upper .Strip to the one below. These fasteners, as best seen in Fig. 5. may consist of fiat metal pieces'havng llwo prongs 22 at one end that project beyond the upper edge of the strip to which the fastener is secured and that are' adapted to penetrate Vinto the butting portion I8 of the lower edge of the next upper strip, The A fasteners are further provided With a downwardly bent prong 2,3 that en,- gages in the underlying strip to hold the Afasteners firmly in place, and they may have preformed openings 24 to receive the nails 2S. The notch '25 between the prongs 22 may be lined up Awith the upper edge of the strip and serves as a .gu-ide fer proper placement of the fasteners. The form of the fasteners is such that they may be cut V`from astrip Aof metal without waste. While fasteners of the form described are preferred, other suitable fasteners may be'used.

In applying the siding, the strips of each course, together with the associated fasteners 12|. are secured in piace by the nails 20, After .one course `of Astrips has been applied, theV strpspl' the next upper course, together with itsassociated fasteners, is then similarly applied and nailed. Use ,of the fasteners greatly factil-itates application .of the siding because each strip `will be held in proper position to be `subsequently nailed by its engagement with the prongs 22 of the fasteners of the next lower strip. Accordingly, one man can easily apply the siding.

The joints formed by the ship-lap edges i3 and i4 of adjoining strips in each course are flush, and are Ypreferalily caulked with a suitable caulle ing cement to which granules, similar tothe granules l2, may be applied to conceal or carnous fiese the jointssirable at :the overlap joints between the strips of succeeding courses. Not only does this effect an economy in caulking cost, but itprovides a sidf ing structure that has breathing charactersf tics, since air may pass through those joints.

No caulking is necessary or de- What I claim is:
